Abstract
In some examples, an apparatus can include a pawl including an anti-rotation surface and a spring, and a valve housing including a wedge, where the spring biases the pawl to a first position in response to the valve housing being at a closed position such that the wedge of the valve housing contacts the anti-rotation surface of the pawl to prevent rotation of the valve housing at the first position of the pawl.
Claims15
An apparatus, comprising:
- a pawl including an anti-rotation surface and a spring;
- and
- a valve housing including a wedge;
- wherein the spring biases the pawl to a first position in response to the valve housing being at a closed position such that the wedge of the valve housing contacts the anti-rotation surface of the pawl to prevent rotation of the valve housing at the first position of the pawl.

A system, comprising:
- a valve housing, including a first wedge and a second wedge;
- and
- a pawl, including:
- an anti-rotation surface that contacts the first wedge to prevent rotation of the valve housing in response to the valve housing being at a closed position;
- an angled surface;
- and
- a leaf spring to bias the pawl to a first position in response to the valve housing being at the closed position;
- wherein the pawl rotates from the first position to a second position in response to the angled surface of the pawl contacting a surface of an imaging device.
5 more elements
A print substance supply, comprising:
- a valve housing, including a first wedge and a second wedge;
- a pawl, including:
- an anti-rotation surface that contacts the first wedge to prevent rotation of the valve housing in response to the valve housing being at a closed position;
- an angled surface;
- and
- a leaf spring to bias the pawl to a first position in response to the valve housing being at the closed position;
- wherein:
- the pawl rotates about a pawl axle from the first position to a second position to cause the anti-rotation surface of the pawl to rotate away from the first wedge of the valve housing in response to the angled surface of the pawl contacting a surface of an imaging device in response to a translational motion of the print substance supply towards the imaging device;
- and
- the valve housing is rotated from the closed position to an open position such that the anti-rotation surface of the pawl contacts the second wedge.
